  [HLSL][LongVector] Implement fmod (#224123)

resolves https://github.com/llvm/llvm-project/issues/220649

This is as much a refactor as it is adding long vector support.

I noticed the fmod helper had many issues. THe SPIR-V implementatiion
wasn't properly put into a SPIR-V macro

fmod had a scalar \ vector version that was unecessary.

The tests seemed to be raw register defines so
source code changes caused the names to all change.

Fixing this meant we could simplify the tablegen
and helpers.

Also the tests are much more clean with no -D defines
